稀土元素的分离、分析,在地球化学、宇宙化学、环境化学等学科中起着极为重要的作用。近年来,国内外利用高分辨率γ谱仪中子活化分析法测定岩石中稀土元素的报道很多,虽然对放射化学分析流程都在不同程度上有所改进,但对超基性岩石中大量存在的~(24)Na、~(46)Sc、~(59)Fe和~(51)Cr等核素的去除,解决被测元素γ谱之间相互干扰(包括重峰干扰和康普顿本底干扰)
The separation and analysis of rare earth elements play an extremely important role in geochemistry, cosmic chemistry and environmental chemistry. In recent years, there are a lot of reports on the determination of rare earth elements in rock by using high-resolution gamma spectrometer neutron activation analysis. Although the procedures of radiochemical analysis are improved to some extent, ~ (24) Na, ~ (46) Sc, ~ (59) Fe and ~ (51) Cr and other nuclides were removed to solve the interference of the γ spectrum of the tested elements (including the heavy interference and Compton Interference at the end)
